IMPROVEMENT IN INJECTING AND DoucHlNGlNsl-RUMENTS.

Specification forming part of Leiters Patent No.' 40,192, lated October (i, 1863;'

To all whom, it may concern:

Be it known that I, JOSEPH SINGER, of Chicago, Cook county, and State of Illinois, have invented a new and useful I njecting and Douching` Instrument; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being` had to the accompanying drawings, making a part ot' this specification, in which- Figure l is a perspective view of my invention. Fig. 2 is an enlarged view showing the condensing apparatus. Fig. 3 is a vertical central section through the instrument. Fig. etis ahorizontal section (enlarged) through Fig. 3, taken' in the plane indicated by red line .r :r thereon. Fig. 5 represents injection and spray tubes.

Similar letters ot' reference indicate correspondin g parts in the several figures.

The object of this invention is to obtain an instrument which shall be simple in its construction and easily cleaned to take the place of medical syringes and in jectors, particularly such as are used in the practice of hydropathy, for administering` douche-baths, elysters, Ste., for showering any diseased part of the body, for introducing` liquids, warm or cold, into the rectum or lower intestines, for promoting alvine discharges, cleansing the bowels, and for many similar purposes where a large quantity of water or other liquid is required, and where it is desired to apply a stream or spray of the liquid to a diseased part of the body externally or internally.

The nature of my invention consists in combining a condensing apparatus, hereinafter to be described, with a tightly-closed vessel of any desired capacity which is suitably lined to resist the action of acids, and which is furnished with a stop-cock to which a iiexible tube is connected, carrying on its end either a clyster-pipe, a rose-nozzle, or any other suitable device which it may be desired to use, all as will be hereinafter described.

It also consists in combining with a tight vessel suitable for containing liquids a condensing-cylinder having a valve in its bottom which opens upward, a supply-pipe for supplying external air to the cylinder, and a discharge-pipe `for conducting the compressed air into the vessel containing the liquid, and above the liquid therein, whereby a constant and uninterrupted ow ot' liquid will be dis-v chargedtunder pressure) from said vessel, as will be hereinafter described.

To enable others skilled in the art to make and use my invention, I will describe its construction and operation.

In the accompanying drawings, A represents a cylindre-conical vessel, which is made of metal, suitably lined to resist the action ot' acids, and closed at its top by a screw-cap or cover, A', thejoints of which are packed as shown at a., Figs. l and 8. Near the bottom ofthe vessel A a stop-cock, B, is inserted, to y the nozzle of which provision is made for securing a flexible tube, C, shown in Fig. l, carrying on its end a spray or rose nozzle, D.

The vessel A is furnished with handles b b, and it may betinished in a very neat and handsome manner.

E is a perpendicular cylinder, which is sccured at its upper end to the cover A', through which it projects a short distance, and receives on its upper end a screw-cap, d, through which passes the rod e of a solid piston, F. The cap d has a hole,f, through it to allow the air above the piston F to escape from cylinder E when-this piston is drawn up. The piston-rod e has a T-handle, e/, on its upper end, and the piston is suitably packed to work up and down perfectly' tight within its cylinder E. In the bottom ot' cylinder E is a valve, g, which is ground tightly and seated on a plate, 7L, that forms a compartment in the bottom ot' the cylinder E, comma,

nicating with which is a tube, G, which eX- tends upward and through the cover A', and

is furnished with a perforated cap, t', on its upper end, the object ot' which cap is to prevent anything which might injure the valve g from getting into the tube G.

In Figs. 2 and 4 I have shown another pipe, H, communicating with the condensing-cylinder E, which is intended for conducting the compressed air in this cylinder and below the piston into the vessel A above the liquid in this vessel. The pipe H communicates directly with the cylinder E above the valve g, and at the lowest point of the descending stroke of the piston. This pipe has a valve, lo, which also opens upward, in its upper end, as shown in Fig. 2 of the drawings. The top of pipe H extends up as near to the bottom of the cover A as possible, to allow the valve K to work freely and to prevent liquids which are put into thevessel A from getting into the pipe H. The vessel A should not, however, be entirely filled, but a space of a few inches must be left between the liquid and the cover of the vessel.

The mode of using the above-described machine is as follows: Water or other liquid whichitis desired to use is introduced through the opening in cover A, which is closed by the air-tight cap a, Fig. 1, and when the vessel A is nearly full this cap a is screwed down tightly in its place. The cock B may now be opened to allow the liquid contained in the vessel A to be forced through the pipe or iieXiblc tube C, which force is obtained by raising` and depressing the piston F by means ofthe T-handle rod e, and thus forcing air through the valve-pipe H into the vessel A and above the liquid contained in this vessel. After several strokes ofthe piston the air above the liquid in vessel A will be very much condensed, and aconstant and uniform elastic pressure may in this manner be brought to act upon the contained liquid, which will be forced ont ot' the vessel through the cock B and iiexihle pipe C in a steady stream. It Will be seen from this description that no liquid passes through the condensing apparatus proper, and that the cylinder E and pipes H G are not subject to the corrosive effect ofthe liquids which are used in the machine, said parts being kept perfectly dry and always in good working condition.

The condensing apparatus may be made very compact, and in machines which are made for ordinary use these parts need not be niade very large, for it will be seen that the g pressure ofthe air in the vessel A may be increased with a very small cylinder to any desired degree by giving a very rapid motion to the piston.

/Vhen the machine is to be used as an injector for introducing liquids into the rectum, the perforated spray-nozzle l) is removed from the tube C and a ciyster-pipe, such as I have shown in Fig. 5, may be applied to the tube; or the swelled tube or nozzle J may be used instead of either for cleansing and injecting liquids through the vaginal canal, for which latter purpose my machine is especially useful. lhen again,in hospitals where water is not very convenient my machine will be found very useful, as it is adapted to contain a large amount of liquid, and will not re- A quire frequent retillin g.

For warm liquids, which are to be applied in this condition, my machine is so constructed that it will coniine the heat within it, more especially it' the vessel A is made with double walls.

The cover Al is removable for the purpose of cleaningand getting at the contained parts, and the whole machine may be taken to pieces and cleaned should the valves or piston leak i in consequence of dust, 85o., getting into them.

I do not claim the employment of an airpump within a vessel to contain liquids for the purpose of giving injections; but

I do claim 1. With an air-pump thus employed the arrangement ofthe pipes G H and the valves g and lc, in the manner set forth.

2. In combination with said pump so arranged, the arrangement ofthe escape-pipe H, extendingwabove the surface of the liquid, as set forth.

JOSEPH SINGER.
